See the guide: FFmpeg (contrib) > Encoding and decoding audio using FFmpeg
Creates an op that encodes an audio file using sampled audio from a tensor.
audio: A rank-2
Tensorthat has time along dimension 0 and channels along dimension 1. Dimension 0 is
samples_per_second * length_in_secondslong.
file_format: The type of file to encode, as a string or rank-0 string tensor. "wav" is the only supported format.
samples_per_second: The number of samples in the audio tensor per second of audio, as an
A scalar tensor that contains the encoded audio in the specified file format.
